Lenovo BIOS image with version 6CCN18WW, shown in brackets as V1.05, using the standard Lenovo numbering where the first characters identify the platform and WW marks a worldwide release. The 4 MB ROM matches a 32 Mbit SPI flash. The name does not state the laptop model, so match the 6CCN prefix against the BIOS version of the target machine. Back up the original chip before writing with a programmer, as mismatched firmware will not boot.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
